[webkit-dev] Removing support for the -khtml- (and -apple-?) vendor prefixes
Good day, While going through WebCore for some CSS research I'm currently doing, I came across a piece of code[1] which translates all "-khtml-" and "-apple-" vendor-prefixes to "-webkit-". This effectively means "-apple-transform" and "-khtml-transform" can both be used instead of "-webkit-transform". I am unaware of the rationales behind the apple vendor-prefix, but I'd like to propose removing support for the KHTML-prefix. My main argument for this is that WebKit and KHTML are, in my opinion, two separate engines by two separate vendors. The port occurred eight years ago, and code in both projects has changed significantly ever since. When Microsoft announced support for "-webkit-text-size-adjust" in IE Mobile it was argued that browsers should not implement properties with prefixes "belonging" to other vendors, which seems to be exactly what WebKit is doing with the KHTML prefix. I understand the history of supporting -khtml-, and I've heard from the KHTML project that they implement the -webkit- prefix as well. However, considering that WebKit has grown significantly in the past few years and that all code changes basically made KHTML and WebKit two individual rendering engines with individual CSS support, I believe it would be appropriate for support to be dropped.

WebKit really uses vendor-prefixed properties for a few different purposes: 1) Properties that are only intended to be used internal to the engine, to implement particular effects. 2) Properties that are future CSS standards but not yet mature enough to remove the prefix. 3) Experimental properties that may be proposed as standards in the future. 4) Proprietary properties that we don't intend to standardize, but which can be used by content. 5) Properties that were once prefixed for one of the above reasons, and we keep the prefixed version in addition to the unprefixed one. One beneficial exercise would be to classify prefixed properties into the above buckets. For categories (3) and (4), we should consider whether the properties in question can actually be proposed as standards, and therefore move to category (2). For category (5), we should assess the compatibility impact of removing the prefixed version.

Re: [webkit-dev] Removing support for the -khtml- (and -apple-?) vendor prefixes
Right now WebKit has by far the most prefixed elements[1], a significant part of which have not been standardized/drafted yet. Keeping the translation for all properties active practically triples the amount of supported vendor-specific CSS extensions, which cannot be desirable. I'm not opposed to the idea of limiting the supported properties for these prefixes to a certain subset, but my preference would be to only support behavioral properties as "-webkit-binding", "-webkit-font-smoothing", "-webkit-highlight" and "-webkit-user-(drag|modify|select)". In the same piece of code, prefixed versions of border-radixes and opacity are still supported as well.

Re: [webkit-dev] Removing support for the -khtml- (and -apple-?) vendor prefixes
The reason for these is historical. Originally, we didn't use a separate vendor prefix for WebKit, just -khtml. Later we changed to -apple. Eventually we realized WebKit would not be an Apple-specific project forever, so we switched to -webkit. The main risk to removing the old prefixes is that some older WebKit-specific content authored against them will break. I'm not sure the code cleanup benefits outweigh the risk of breaking content. If we want to phase out support for these older prefixes, what I'd propose as a first step is supporting the legacy prefixes for old properties but not for any new ones.

There was a incident about a year ago where MediaWiki had a work-around for a very old KHTML bug and we had to add a special work around for MediaWiki for the compatibility. (See https://bugs.webkit.org/show_bug.cgi?id=28350). Later, we found that there are various websites that uses 3 years old or older copies of MediaWiki.

Re: [webkit-dev] Removing support for the -khtml- (and -apple-?) vendor prefixes
While converting all -khtml- properties to -webkit- may not be appropriate because there could be incompatible implementation of certain property, there are properties starting with -khtml- that are supposed to be supported by WebKit. See bugs such as https://bugs.webkit.org/show_bug.cgi?id=11825. Not supporting these will be a burden for some Web developers as they need to add both -khtml- and -webkit- to specify one property.

[webkit-dev] Removing support for the -khtml- (and -apple-?) vendor prefixes
Good day, While going through WebCore for some CSS research I'm currently doing, I came across a piece of code[1] which translates all "-khtml-" and "-apple-" vendor-prefixes to "-webkit-". This effectively means "-apple-transform" and "-khtml-transform" can both be used instead of "-webkit-transform". I am unaware of the rationales behind the apple vendor-prefix, but I'd like to propose removing support for the KHTML-prefix. My main argument for this is that WebKit and KHTML are, in my opinion, two separate engines by two separate vendors. The port occurred eight years ago, and code in both projects has changed significantly ever since. When Microsoft announced support for "-webkit-text-size-adjust" in IE Mobile it was argued that browsers should not implement properties with prefixes "belonging" to other vendors, which seems to be exactly what WebKit is doing with the KHTML prefix. I understand the history of supporting -khtml-, and have heard from the KHTML project that they implement the -webkit- prefix as well. However, considering that WebKit has grown significantly in the past few years and that all code changes basically made KHTML and WebKit two individual rendering engines, with individual CSS support, I believe it would be appropriate for support to be dropped.
